I can get one scary sharp but they don't hold that type of edge very long. The sharper the knife, the thinner the edge the quicker it dulls.
I agree and that's the way I like my knives even though I may have to sharpen them often. But the harder the metal, the less you will have to sharpen them. But the softer the metal, the sharper I can get them. I have found my best sharpener lately to be a diamond jewelstick.
For my two and four bladed broadhead, I use an s-24 sharpener.
